MONSTERIOUS is Matt McMann’s spooky middle grade monster mystery series, great for fans of Goosebumps, Stranger Things, or Five Nights at Freddy’s. The books are short, can be read in any order, publish in all formats simultaneously, and come out quickly. While geared for ages 8-12, they are perfect for anyone who enjoys fast-paced thrillers with lots of action, humor, and heart.

In ESCAPE FROM GRIMSTONE MANOR, three friends are trapped overnight in a haunted house amusement park ride and discover the monsters are real.

In THE SNATCHER OF RAVEN HOLLOW, two friends learn that a monster is behind the disappearance of babies in their small town—but no one believes them.

In TERROR IN SHADOW CANYON, five hikers lost in a remote wilderness are stalked by a flesh-eating monster.

In THE BEAST OF SKULL ROCK, a brother and sister attempt to save their grandfather’s creepy cabinet of curiosities museum from a rampaging werehyena.

In TRAPPED IN THE HORROR DOME, a 7th grade field trip to a science biodome becomes a nightmare when a terrifying monster escapes from a secret lab.

While primarily fun spooky adventures designed to help kids love reading, MONSTERIOUS books explore themes of friendship, courage, loyalty, sacrifice, and self-acceptance.
